According to a police report, Bullitt County sheriff's deputies were called to a Shepherdsville home Sunday around 9 p.m. after a verbal argument between Knowles and his girlfriend escalated.

Police said the girl's stepfather intervened in that verbal altercation and blows were exchanged between Knowles and the girl's stepfather. The stepfather was struck in the left eye.

"At some point there, Mr. Knowles stated that the victim's father had shoved him and he, in defense of himself, stated he had hit the victim's stepfather in this case," Bullitt County Detective Scotty McGaha said.

Police said the stepfather received minor injuries. He has been referred to the county attorney's office to make a statement on misdemeanor assault.

"In this case, the victim's stepfather was referred to the county attorney on what we call misdemeanor assault. He has some minor injury," McGaha said.

He has not made that statement yet, but WLKY was told he will be meeting with the Bullitt County Sheriff's Department on Wednesday.

WLKY was sent a picture of the man's injuries at 9:50 p.m. Sunday. Police said that's the night the stepfather was injured. WLKY received a second picture the next day.

No one was arrested or has been charged in this incident.

"We don't make an arrest, no police officer does, if it's not in their presence, if it's a minor assault," McGaha said.

According to the university's student-athlete code of conduct, athletes are considered "public figures on campus and in the community and are expected to conduct (themselves) in an appropriate manner."

It goes on to state, "any violation of state or federal law ? may result in temporary loss of practice or participation status, indefinite team suspension and dismissal from the team."

The University of Louisville said they are aware of this incident. WLKY faxed them a copy of the police report, but the university has not made any comment.

McGaha said authorities met with Knowles and a friend who witnessed Sunday night's incident, Tuesday night.

Knowles was interviewed for two hours and is cooperating with the investigation. Knowles was accompanied by his attorneys.

The stepfather and family will be meeting with authorities Wednesday.

Authorities are not releasing any more details in this ongoing investigation.
